Description for technical specifications<br />
The AC8 and the PCU32 represent a modular control and surveying system for the evacuation of smoke and heat and to control climatic<br />
variations such as rain and wind. The module system has been designed to allow the customer great flexibility to implement and to program<br />
the system according to specific requirements.<br />
The AC8 control unit can be connected up to a max of 31 units by means of a RS485 serial line. The AC8 can be employed in three<br />
different application systems:<br />
• SINGLE: only one AC8 unit to control one single area (connection of 24V voltage motors for max. 16A)<br />
• MULTIPLE: more than one units, to control various areas simultaneously (max 31)<br />
• COMBINED MULTIPLE: to control more areas from one single point (many AC8 units and 1 PCU32 display).<br />
The PCU32 module, equipped witn a LCD display, displays and monitors the status of all the AC8 control units connected to it and control<br />
them in single or multiple way. It has the buttons for the general co<strong>mm</strong>and and the matrix to display the status of the peripheral modules<br />
of each zone.<br />
This innovative system allows to place the AC8 module close to the motors to control. Each system’s configuration can be further implemented<br />
with the MEM/AL optional module that allows the connection of 24V motors for max. 16A. It just feeds the motors while the AC8 operates<br />
them. A wide choice of accessories, such as electric sirens, flashing lights and automatic dials can be connected to the AC8 and the PCU32<br />
units. The alarm caused by smoke, gas and temperature sensors is prior to every other function. Each MEM/AL module is supported by<br />
a feeder and batteries; the connection between control unit and MEM/AL module does not need particular wires<br />
but a standard cable with minimum diameter. The AC8 control unit can work also with 230V motors: if controlled by the M5 module they<br />
can be used for ventilation. All detectors (wind/rain/smoke/gas, etc. sensors) can be connected to the M5, that independently processes<br />
the emergency and operates the window. A battery pack at 24V and buffer charged ensures the power supply to the connected safety<br />
sensors for 72 hours avoiding any power loss and useless long wiring costs. The feeding unit is contained in shockproof grey plastic, with<br />
IP55 protection rating. CE marked device complying with the following regulations: EEC 89/336, EEC 73/23 and following amendmens.<br />
